Biomedical electrode and wearable electrode

Abstract

A biomedical electrode which is detachably attached to a garment and includes: an electrode coming into contact with a living body clothed in the garment to acquire a biological signal emitted by the living body; and a locked section which is conductive, is electrically connected to the electrode, is detachably locked to a locking section which is conductive and is provided in the garment, and is electrically connected to the locking section when locked to the locking section.

The invention claimed is: 
     
       1. A biomedical electrode which is detachably attached to a garment, the biomedical electrode comprising:
 an electrode coming into contact with a living body clothed in the garment to acquire a biological signal emitted by the living body; 
 a locked section which is conductive and electrically connected to the electrode, the locked section being detachably locked to a locking section which is conductive and provided in the garment, wherein the locked section is electrically connected to the locking section when locked to the locking section; 
 a connection wiring electrically connected to the locking section; and 
 a loop section provided on the garment such that the loop section is spatially separated and disposed vertically from the locking section, the connecting wiring passing through the loop section. 
 
     
     
       2. The biomedical electrode according to  claim 1 , comprising a coating member configured to cover the locked section. 
     
     
       3. The biomedical electrode according to  claim 1 , wherein at least a part of the locked section is embedded in the electrode. 
     
     
       4. The biomedical electrode according to  claim 1 , wherein the locked section is a button. 
     
     
       5. The biomedical electrode according to  claim 4 , wherein the button is a male button or a female button of a dot button. 
     
     
       6. A wearable electrode comprising:
 the biomedical electrode according to  claim 1   
 wherein the electrode is formed of a conductive fiber structure which is a fiber structure impregnated with a conductive polymer. 
 
     
     
       7. The wearable electrode according to  claim 6 , wherein the conductive fiber structure is obtained by impregnating the fiber structure with a conductive polymer by applying a liquid dispersion, which is obtained by dispersing the conductive polymer and a binder in a solvent, to the fiber structure. 
     
     
       8. The wearable electrode according to  claim 6 , wherein the conductive polymer includes a mixture of poly3,4-ethylenedioxythiophene and polystyrene sulfonic acid.
